The Aluminum Cable Stabilizer Stair Kit is designed specifically for stairs where post to post measurement spans over 4′. It enables you to adapt longer spans to code compliancy by stabilizing the deflection of cable between posts. Each kit comes with a 42″ stanchion pre-slotted to work with our standard 3″ cable spacing. In most cases, stanchions must be field cut at both ends for an accurate fit. This kit cannot be used to replace the use of substantial mid posts and should never be used in spans over 7′. Kit includes fasteners.
